“Soft words turn away wrath, as harsh words excite wrath even in a gentle spirit: forgiveness will melt the most arrogant heart, as punishment will harden even the humblest…. I do not mean by this that we must spare all criminals without distinction: for there is such a thing as an incurable and persistent depravity on which kindness is wasted. A man who offends in this way should be removed at once as a cancer in the body politic.
